To @ZZ lwhom t may concern Be it known that We, LARs G. NlLsoN and J nuns ABEGG, citizens of the United States, residing at Hoboken, N. J., have invented certain new and useful Improvements in Stylographic F ountain-Pens, of which the following is a clear, full, and exact description.

This invention relates to an improvement in stylographic pens and has for its object to simplify the construction of the same and to obtain improved results therefrom.

Stylographic pens as at present constructed usually have a writing member consisting of a ne wire forming a single needle-like Such a writing point has very little flexibility, and, moreover, when the ink dries thereon between the different times when itl is used, it is apt to become clogged and prevent the easy flow of ink to the paper. To overcome these objections we propose a writing member formed of a plurality of needle-like wires closely bundled together tov provide ink flowing channels along their adjacent sides and between them, their support as to b e capable of independent flexing movement and thus insure from at all times.

We also propose forming the different parts of the pen in sucha way as to make them easily detachable for cleaning and for lling the pen, and for the purpose of re.- placing worn out or broken parts.

A still further object is to provide a con` struction wherein the How of ink to the writing point may be adjusted for iine or heavy lines and to even be. shut olf entirely when desired. j

Other objects and advantages of our new construction will become'apparent from the following detailed description and accompanying drawings.

In the drawings which show `the preferred writing point.

embodiment of our invention, Figure .1 is .a view of the entire pen; i Fig. 2 is an enlarged detail of the lower end thereof partly in section;

Fig. 3 is a view of the main point section and supplemental point section, the former .being in longitudinal section;

Fig. 4 is a detail longitudinal section through the main point section and supplemental point section, showing the mounting of the feed-bar and the writing member;

an easy flow of ink thereas shown at Fig. 5 is a cross-section along line 5 5 of Fi 3;

Fig. 7 is an enlarged detail of the lower portion of the writing member; and

Fig. 8 is a top end view of the feed-bar.

9 vis an enlarged detail of the writing mem er with the front wire removed.

Referring more particularly tothe drawings, the. pen comprises the usual ink barrel- 5 having an ink reservoir 14 within the same, a cap 6, main point section 2, supple- Lnental point section 1, and a writing mem- The main point section may be mounted upon the barrel of the pen by screw-threaded engagement therewith as is customary, and within the main point section and carried thereby is preferably mounted the feed-bar 3,- also screw-threaded therein as shown.

The upper end of the feed-bar communicates with the interior of the ink reservoir 14 and has ink feeding grooves 9 along its sides leading toward the lower end thereof. The lower portion of the feed-bar is preferably tapered as shown in Fig. 4, and has securely fixed in its lower 'end at 15 the writing member 4.

The writing member 4 is formedy to provide a plurality of separate and co-acting needle'iike points and consists preferably of a number of in dependent straight wires laid contiguously in parallel relation, as shown in Figs. 6 and 7, so as' to provide ink flowing channels 4 them. The number of wires thus bundled together may be varied, although we prefer lthree or more wires laid together, and in the present embodiment have shown four of such wires. The. wires terminate evenly, and their lower ends are also preferably tapered, 9, to a common central axis of the group and thus provide a line markin element which is suitable for writmg an whiclf will give service upon any side of the writing member which ,happens to be put against the paper, as in the case of the ord1 nary stylographic needle point. Moreover, since the separate wires making up the Writing member are independently mounted, they have a flexing movement vone upon the other in use and thus tend to break up clots of of in dried ink thereon and insure an easy flow k t9 the point of application on the paper. rllhe writing member may of course be formed in other ways than by the bundling of wires together as we have, shown, the essential feature being to provide a plu- .rality of such coacting needle-like points.

The writing member 4, as it extends from within the main point section 2, is inclosed within a supplemental point section l preferably screw-threaded at its upper end within the lower end of the main point section 2. The lower end of the supplemental point section 1 is provided with the usual bushing of metal 10. rlhe inner peripheral corner 12 at the upper end of the supplemental point section l is adapted to engage the lower tapered portion of the feedbar 3 at a line below the ink feeding grooves 9 and the supplemental point section 1 may be adjusted on its screw-threaded engagement with the main point section 2 to bring about this contact or to vary the space betweenthe edge 12 of the supplemental point section and the feedbar 3 to adjust the flow of ink down the feed-bar and on to the writing member 4. Of course when the supplemental point section 1 is screwed tightly to bear against the feed-bar 3, the flow of ink is entirely shut off. The enlargedI threaded upper end of the supplemental point section 1 is preferably provided with a slot 7 with perforations 8 extending therefrom through the wall of said supplemental point section 1 and thus provide an air vent to the space surrounding the feed-bar. Thisprovides for atmospheric pressure within the ink reservoir to permit the easy How of ink therefrom, asis well understood.

We do not wish our invention to be limited to the specific constructions above described and shown in the drawings, as it is obvious that various changes in detail and arrangement of the parts may be made without departing from the essential characteristics of the invention.

What we claim as new is 1. A stylographic writing pen comprising a plurality of contiguous straight wires coacting at one end to form a stylographic point suitable for writing., j

2. A stylographic writing member comprising alplurality of contiguous straight y of June, 1916.

naaaovo wires with their ends terminating evenly and coacting to form a stylographic writing point.

3. A stylographic writing member comprising a plurality of contiguousstraight wires laid together to provide ink flowing channels between their sides and with their ends terminating evenly and coacting at said ends to form a stylographic writing point.

4. A stylographic writing member comprising a plurality of contiguous straight wires independently flexible with their ends terminating evenly and coacting at said ends to form a stylographic writing point.

5. A stylographic writing member comprising a plurality of contiguous straight wires with evenly terminating ends tapered toward a common central aXis of the group, said ends coacting to form a stylographic writing point.

6. In a stylographic pen, in combination, a pen holder, a writing member comprising a plurality of contiguous straight wires supported in said holder and Vcoacting at one end to form a stylographic writing point, and a member embracing said wires for supporting the same adjacent the writing point.

A stylographic writing member comprising, in combination, a feed bar, a plurality of wires fixed at one end in said feed bar and laid contiguously with their other ends terminating evenly to form coacting writing points, and a point section inclosing said contiguous wires and forming a bearing support therefor slightly above the writing points. i

8. Al stylographic writing member, comprising a plurality of independently mounted wires normally in contact throughout their length and coacting at their .free ends to form a stylographic .writing point and a member embracing said wires for supporting the same adjacent the writing point.
